FLEXlm log file
Read this to familiarize yourself with the FLEXlm log file.
The FLEXlm license server daemons log messages about the state of the license server
hosts, and when licenses are checked in or out. This log helps to resolve problems with
the license server hosts and to track license use. The log file grows over time. You can
remove or rename the existing FLEXlm log file at any time.
You must choose a location for the log file when you start the license daemon. If you
already have FLEXlm server running for other products and Platform LSF licenses are
added to the existing license file, then the log messages for FLEXlm should go to the
same log file you set up for other products. If FLEXlm is dedicated to managing LSF
licenses, you can put the FLEXlm log in the same directory as your other system logs,
or in the
/tmp directory.
License management utilities
FLEXlm provides several utility programs for managing software licenses. These
utilities and their man pages are included in the Platform LSF software distribution.
Because these utilities can be used to shut down the FLEXlm license server daemon,
and can prevent licensed software from running, they are installed in the
LSF_SERVERDIR directory. For security reasons, this directory should only be
accessible to LSF administrators. Set the file permissions so that only root and members
of group 0 can use them.
LSF installs the following FLEXlm utilities in
LSF_SERVERDIR:
lmcksum
Calculate check sums of the license key information
lmdown
Shut down the FLEXlm server
lmhostid
Display the hardware host ID
lmremove
Remove a feature from the list of checked out features
lmreread
Tell the license daemons to re-read the license file
lmstat
Display the status of the license server daemons and checked out licenses
lmver
Display the FLEXlm version information for a program or library
For complete details on these commands, see the FLEXlm man pages.
